The SoSoundElement is used for optimizing audio rendering and for turning off inactive SoVRMLSound nodes.
SoSoundElement::~SoSoundElement | ( | void | ) | [protected, virtual] |
The destructor.
void SoSoundElement::initClass | ( | void | ) | [static] |
This static method initializes static data for the SoSoundElement class.
Reimplemented from SoReplacedElement.
void SoSoundElement::init | ( | SoState * | state | ) | [virtual] |
Initializes the element to it's default value.
Reimplemented from SoReplacedElement.
SbBool SoSoundElement::setSceneGraphHasSoundNode | ( | SoState *const | state, |
SoNode *const | node, | ||
SbBool | flag | ||
) | [static] |
Sets the sceneGraphHasSoundNode flag.
SbBool SoSoundElement::sceneGraphHasSoundNode | ( | SoState *const | state | ) | [static] |
The sceneGraphHasSoundNode flag is used to stop the SoAudioRenderAction in SoSeparator and SoVRMLGroup nodes for cases where the sub-graph doesn not contain any SoVRMLSound nodes.
Returns the value of the sceneGraphHasSoundNode flag.
SbBool SoSoundElement::setSoundNodeIsPlaying | ( | SoState *const | state, |
SoNode *const | node, | ||
SbBool | flag | ||
) | [static] |
Sets the soundNodeIsPlaying flag.
SbBool SoSoundElement::soundNodeIsPlaying | ( | SoState *const | state | ) | [static] |
The soundNodeIsPlaying flag is currently unused.
Returns the value of the soundNodeIsPlaying flag.
SbBool SoSoundElement::setIsPartOfActiveSceneGraph | ( | SoState *const | state, |
SoNode *const | node, | ||
SbBool | flag | ||
) | [static] |
Sets the isPartOfActiveSceneGraph flag.
SbBool SoSoundElement::isPartOfActiveSceneGraph | ( | SoState *const | state | ) | [static] |
The isPartOfActiveSceneGraph flag is used to make SoVRMLSound that are below inactive parts of the scenegraph (i.e. below a SoSwitch or SoLOD node) stop playing.
Returns the value of the isPartOfActiveSceneGraph flag.
void SoSoundElement::push | ( | SoState * | state | ) | [virtual] |
Calls the superclass' push method. Initializes the element to the default values. Uses previous element's isPartOfActiveSceneGraph flag.
Reimplemented from SoElement.
void SoSoundElement::setDefaultValues | ( | ) | [protected] |
Initializes the element to the default values. The default values for the sceneGraphHasSoundNode is FALSE. The default value for the isPartOfActiveSceneGraph flag is TRUE. the default value for the soundNodeIsPlaying flag is FALSE.
